Detailed Description

The utility model provides a shoe pad. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.

The insole is fixed in the shoe body in a limited mode, as shown in fig. 1 and 2, a protruding part 2 for applying functional pressure to the sole is arranged on a supporting surface of an insole body 1, the protruding part 2 is provided with a protruding supporting surface 3 for the sole, smooth transition is arranged between the protruding supporting surface 3 and the supporting surface of the insole body 1, a projection area of the insole body 1 corresponding to the protruding supporting surface 3 is a hollow part 5, and the hardness of the protruding part 3 is larger than that of the insole body 1.

Specifically, the traditional insoles are all flat layered structures, the support for the sole of the foot is mainly designed at the bottom of the shoe, and some functional insoles are provided, and the surface support cannot be realized through a support column structure.

More specifically, as shown in fig. 3, the raised support surface 3 covers the seed bone, the inner wedge bone, the middle wedge bone, the outer wedge bone, the navicular bone, and the sustentaculum talinum of the first metatarsal, and the boss portion 2 includes an arc-shaped outer edge 4 extending from the seed bone to the sustentaculum talinum, and the arc-shaped outer edge is away from the outer edge of the insole.

The foot sole support device can realize the shape-following support of the foot sole, does not need to select professional health care shoes, is suitable for various common shoes, and plays the roles of relieving fatigue and adjusting body posture.

In one embodiment, the insole body 1 is a breathable insole body, and the protrusion 2 is fixedly disposed on the breathable insole body 1. The air permeability requirement of the insole is met.
